Domain Spoofing Defined And Why It Works
- Domain spoofing is when attackers create malicious domains that closely mimic legitimate ones to trick victims.
- Rick Howard explains defenders must use layered controls because no single solution fully prevents it.
Real-World Penta Bank Example
- Rick Howard cites the 2021 Penta Bank example where attackers registered getpenta-bank to harvest logins.
- The spoofed site tried to collect customer credentials by imitating the real getpenta.com domain.
Defend With Layered Controls And Training
- Use layered defenses like anti-spam, SSL validation, DMARC, and DKIM to reduce domain-spoofing risk.
- Train employees through security awareness programs so they can spot spoofed domains and phishing attempts.
